Once seen, it cannot be unseen. The “Mars rat” captured by Curiosity’s lens.

This image taken by NASA's Mars rover Curiosity on Jan. 10, 2013 shows a rock that looks a bit like an iguana (upper right).

A Martian surface feature, as seen on the Google Mars database, that one man says looks like the profile of Mahatma Gandhi.

Mars Face Makeover: Controversial Formation Observed from New Angles

A perspective view showing the so-called 'Face on Mars' located in the Cydonia region. The image shows a remnant massif thought to have formed via landslides and an early form of debris apron formation. The massif is characterized by a western wall that has moved downslope as a coherent mass. The image, created with data from the Mars Express orbiter, was released Sept. 21, 2006.

Bunny Rabbit on Mars

Credit: NASA/JPL

This photo from NASA's Mars rover Opportunity shows what at first glance appears to be a bunny rabbit head on the Red Planet. The image was released in March 2004 in the "mission success" panorama, and the bunny is an illusion likely created by a piece of Vectran cloth from Opportunity's lander.

Mars Rover Spirit's 'Phallic' Tracks

NASA's Spirit Mars rover created these tracks shortly after touching down in 2004 to execute a turn, not amuse its handlers.

Strange Mars Photo Includes Tantalizing 'Tree' Illusion

Credit: NASA/JPL/University of Arizona.

This new image of Mars taken by NASA's Mars Reconnaissance Orbiter shows an optical illusion. What appears to be trees rising from the Martian surface are actually dark streaks of collapsed material running down sand dunes due to carbon dioxide frost evaporation. The image was released in Jan. 2010.

Secret Mars 'Bio Base'?

A mysterious object spotted on the surface of Mars by David Martines while he was perusing the planet using Google Mars, a mapping program. What Martines described as a Martian "Bio Base" is actually an artifact caused by a cosmic ray interference, experts say.
